suatu fungsi dirumuskan f(x) = px+q. Jika f(-2)=14 dan f(3)= -1, hitunglah nilai p dan q

f(x) = px + q
f(-2) = p (-2) + q
14 = -2p + q
14 + 2p = q

f(3) = p (3) + q
-1 = 3p + q
-1 = 3p + (14 + 2p)
-1 = 5p + 14
-1-14 = 5p
-15 = 5p
p = -3

q = 14 + 2p
= 14 + 2 (-3)
= 14 - 6
= 8

Jadi, Nilai p = -3 dan q = 8.
